Why Choose the Lovato P1RB1NC10A030 RCBO?
The Lovato P1RB1NC10A030 is a compact and reliable residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against earth leakage, overloads and short circuits. Part of the professional Lovato Electric P1RB series, it combines residual current and miniature circuit breaker functions within one modular protection device.
Featuring a rated current of 10 A, a rated residual operating current of 30 mA and a Type C overcurrent tripping characteristic, the P1RB1NC10A030 is suitable for circuits supplying equipment with moderate starting currents. Its Type A residual current characteristic detects sinusoidal AC and pulsating DC residual currents, making it suitable for installations containing modern electronic equipment.
The RCBO has a 1P+N configuration, occupies two DIN modules and offers a short-circuit breaking capacity of 10 kA. Its compact DIN rail-mounted construction provides a space-efficient protection solution for industrial control panels, commercial distribution boards, machinery circuits and building automation systems.

Combined Residual Current and Overcurrent Protection
The Lovato P1RB1NC10A030 combines the functions of a miniature circuit breaker and a residual current device. Its thermal element responds to sustained overloads, while the magnetic element rapidly disconnects the circuit when a high short-circuit current occurs.
The residual current element continuously monitors the current balance between the live and neutral conductors. If a leakage current reaches the 30 mA operating threshold, the RCBO disconnects the circuit to help reduce the risk of electric shock, equipment damage and electrical faults.
Typical Applications
- Industrial electrical control panels.
- Machinery control and auxiliary circuits.
- Commercial electrical distribution boards.
- Electronic equipment and power supplies.
- Lighting and small power circuits.
- Building control and automation systems.
- Manufacturing and processing equipment.
- Circuits requiring 30 mA Type A residual current protection.
